Catalytic properties and stability of cubic mesoporous LaxNiyOz/KIT-6 catalysts for CO2 reforming of CH4

Abstract A series of Ni based catalysts with KIT-6 and SBA-15 as support were prepared by a sol–gel method. The effect of reaction temperature, catalyst composition and support on the performance of the catalyst was investigated. CH 4 and CO 2 conversion over La 2 NiO 4 /KIT-6 reached 100% when the reaction temperature was increased to 800 °C with GHSV of 3.36 × 10 4  mL g −1  h −1 and CO 2 /CH 4 molar ratio 1.1:1. Among La 2 NiO 4 /KIT-6, LaNiO x /KIT-6 and LaNi 2 O x /KIT-6 catalysts, La 2 NiO 4 /KIT-6 presented the highest activity and stability. This was possibly due to the fact that after reduction of the catalysts, La 2 O 3 acted as a barrier and suppressed the aggregation of Ni particles during the reaction. With the increasing amount of La 2 O 3 promoter, Ni particles were homogeneously distributed. Meanwhile, when compared with La 2 NiO 4 /SBA-15, stability test showed that deactivation rate of La 2 NiO 4 /SBA-15 was faster than that of La 2 NiO 4 /KIT-6. This corresponded to the unique cubic structure of KIT-6, which was favorable for the diffusion of the reactant molecules during the reaction.
